Abstract
【解決手段】照明基板71に接続される2つの電極72aからなる電極部と、この電極部上部に形成される照射部72bとを有するとともに、照射部72bの長手方向の端面72b1が、電極部の端面72a1より短い段形状に構成される複数のLED72を、長手方向が撮像手段8の結像レンズ83を中心とし、かつ結像レンズ83の光学的特性で決まる視野範囲より広い半径からなる円周A方向に沿ってそれぞれ配置する。
【選択図】 図4
Description
図1は、本発明にかかる被検体内導入装置を含む無線型被検体内情報取得システムの全体構成を示す模式図である。なお、この無線型被検体内情報取得システムでは、被検体内導入装置として、被検体である人間の口などから体腔内に導入して、体腔内の被検部位を撮影するカプセル型内視鏡を一例として説明する。図1において、無線型被検体内情報取得システムは、無線受信機能を有する受信装置2と、被検体1内に導入され、体腔内画像を撮像して受信装置2に対して画像信号などのデータ送信を行うカプセル型内視鏡3とを備える。また、無線型被検体内情報取得システムは、受信装置2が受信した画像信号に基づいて体腔内画像を表示する表示装置4と、受信装置2と表示装置4との間でデータの受け渡しを行うための携帯型記録媒体5とを備える。
図7は、図1に示した実施の形態2にかかる照明基板を前面から見た断面図である。なお、以下の図において、実施の形態1と同様の構成部分に関しては、説明の都合上、同一符号を付記するものとする。
図9は、図1に示した実施の形態3にかかる照明基板を前面から見た断面図である。図において、実施の形態2と異なる点は、段形状のLED72を、長手方向がこの撮像手段8の結像レンズ83を中心とし、かつ結像レンズ83の光学的特性で決まる視野範囲より広い幅で半径方向から傾斜して渦巻形状に、それぞれ配置される点である。
